Peel green plantain. Discard skin and cut plantain to 1/2" cubes. Rinse under running water.
In a "Kadai" or frying pan, heat oil. Add garlic and fry until light golden brown. Add dry spices and salt. Add plantains. Stir well. Cover and cook until tender. Do not add water. During the last 2-3 minutes of cooking process, uncover lid and fry on high heat until plantains get a little crunchy on the outside. Adjust seasoning.
